Question

Autoclave method is used to determine (a) residue (b) expansion (c) heat of hydration (d) sulfur content

Answer 1

Autoclave method is used to determine  (b) expansion

• In the field of science, we can describe an autoclave test as a test of delayed expansion for hydraulic cement.
• In this test,  hydration of CaO and MgO cause a delayed expansion and the autoclave method provides a  index of potential for it.
• There are two methods which are used for measuring the expansion of cement or the soundness of cement. One is the  Le Chatelier method and the other is the autoclave method.
• Hence, the correct option is (b) expansion.

Answer 2

Answer:

The autoclave method is used to determine expansion.

• Autoclave functions similar to a pressure cooker and works on the principle of general laws of gases.

• an autoclave is particularly useful for media containing water that cannot be sterilized by dry heat .

other uses of autoclaves are. for sterilizing

• surgical instrument
• culture media
• used to determine
• autoclave plastic
• solution and waautoclavesazards waste
• glassware

Types of autoclave are

• gravity displacement
• vertical type
• positive pressure
• negative pressure
